Tokyo, 2030. A pandemic called Gibiate, which transforms all regardless of age, sex, or race into monsters known as Gibier, has spread throughout the world. This is the age that the samurai, Kanzaki Sensui, and the shinobi, Sanad Kenroku, find themselves in after traveling through time from the Edo era to meet the Doctor and his assistant, Funada Kathleen. What future lies in store for Sensui and Kenroku as they face these monsters for the first time?
I never imagined I'd run into 
a real samurai while I still lived.
لم أتصوَّر أن أقابل ساموراي حقيقيّاً
قبل أن أموت
Hätte nicht gedacht, dass ich zu meinen Lebzeiten
noch mal einem Samurai begegne.
No esperaba conocer
a un samurái real en mi vida.
No esperaba conocer a un samurái real
en mi vida.
Si on m’avait dit que je rencontrerais
des samouraïs de mon vivant !
Non avrei mai immaginato di incontrare
dei veri samurai durante la mia vita.
Nunca imaginei que encontraria um
samurai de verdade na minha vida.
Я и подумать не мог, что встречу
настоящего самурая.
